Distribution

Breeds from Mexico and Texas to central Panama, mostly migrant with wintering grounds from Colombia and Venezuela south to Brazil and Bolivia. A few are probably present during any month in Panama4.

Taxonomy

This species is considered a monotypic species by Clements1 while others recognize more subspecies: flavoviridis, forreri, and insulanus by Restall2 or not insulanus but instead perplexus in Avibase (probably from Dickinson3).

Yellow-green Vireo was for a while considered conspecific with Red-eyed Vireo.

Habitat

Seems plastic in its habitat choice, mostly in open and semiopen areas when breeding in Panama4 but more in forest and semiopen areas in South America during winter2.

Behaviour

Breeding

The female builds a cup shaped nest from plant materials. The clutch consists of 2-3 white eggs with brown marks, which are incubated by the female. Both adults feed the young.

Diet

The diet includes insects gleaned from tree foliage, especially caterpillars and beetles, also small fruits, including mistletoe berries.
